In power electronics fields such as power management, motor drives and new energy storage, power stage devices are the core components for achieving electrical energy conversion, transmission and regulation. TI has established a comprehensive power stage product portfolio covering both traditional silicon (Si) and third-generation semiconductor gallium nitride (GaN), catering to the full range of applications from low-voltage consumer electronics to high-voltage industrial systems and new energy vehicles. Whilst silicon power devices dominate the general-purpose market due to their proven reliability and cost-effectiveness, gallium nitride (GaN) power devices have become the preferred choice for high-end, lightweight and highly efficient power supply solutions, thanks to their technical advantages of high frequency, high efficiency and high power density.

I. TI Silicon (Si) Power Devices: Mature, General-Purpose Power Solutions

Silicon-based power semiconductors are the traditional mainstream solution in the power electronics industry. Following decades of technological iteration, their process systems, mass production systems and application ecosystems have reached full maturity. TI’s silicon power stage products, centred on silicon MOSFETs, integrated power stages and IGBT power modules, are characterised by high reliability, low cost and broad adaptability, making them the optimal value-for-money choice for medium- and low-voltage, medium- and low-frequency power applications.

1. Core Technologies and Product Features

TI’s silicon power stage devices are based on mature silicon wafer processes, with core characteristics tailored to the needs of general-purpose industrial and consumer electronics applications. The devices feature controllable on-state losses, a wide range of voltage ratings, and a stable operating temperature range, with a maximum junction temperature of up to 125°C, making them fully suited for continuous, stable operation under standard operating conditions. Compared to wide-bandgap devices, the core advantages of silicon power stages lie in their extremely high level of technological maturity, excellent parameter consistency, strong immunity to interference and high mass production yield, which can significantly reduce the R&D and production costs of end products.

Furthermore, TI has carried out in-depth integration optimisation on its silicon power device products; several models incorporate gate drivers, protection circuits and freewheeling structures, simplifying peripheral circuit design and reducing the complexity of PCB layout. Their switching frequencies are typically suited to conventional applications ranging from tens of kHz to hundreds of kHz; whilst not matching the high-frequency characteristics of gallium nitride, they fully meet the operational requirements of the vast majority of traditional power supplies, motor drives and lighting power supplies.

2. Mainstream Product Portfolio and Core Advantages

TI’s silicon power stage product line covers the full range of low-voltage (20 V–100 V) and medium-voltage (200 V–600 V) devices, including discrete silicon MOSFETs, integrated power stages and synchronous buck power modules. The products feature built-in overcurrent, overtemperature and overvoltage protection functions, offering high fault tolerance and suitability for complex industrial environments.

Their core competitiveness centres on three key points: firstly, significant cost advantages, with mature manufacturing processes substantially reducing the cost per device, making them suitable for high-volume mass production; secondly, a comprehensive ecosystem, compatible with traditional power supply topologies, driver circuits and control solutions, resulting in low R&D and debugging complexity; and thirdly, long-term proven reliability, with widespread application in various types of equipment operating continuously over extended periods and an extremely low failure rate. In terms of power density, TI’s standard silicon power stage solutions offer a power density of approximately 40–95 W/in³, meeting the space requirements of conventional equipment.

3. Typical Application Scenarios

TI’s silicon power stage products are primarily suited to medium- and low-frequency applications where space constraints are not particularly stringent and strict cost control is required. These include power supplies for consumer electronics, motor drives for household appliances, industrial low-voltage variable-frequency drives, LED lighting power supplies, standard adapters, and battery charging and discharging modules. For example, in motor drive circuits for domestic air conditioners and washing machines, power conversion modules for desktop computers and standard mobile phone chargers, and small industrial regulated power supplies, silicon power stages can achieve stable, efficient and low-cost power conversion.

II. TI Gallium Nitride (GaN) Power Stage Products: A New Generation of High-Frequency, High-Efficiency Power Solutions

As a third-generation wide-bandgap semiconductor material, gallium nitride has surpassed the physical performance limits of silicon. TI has specialised in GaN power technology for many years and has launched a comprehensive range of integrated GaN power stage products. Moving away from traditional discrete component designs, these products highly integrate GaN power transistors, high-speed gate drivers and precision protection circuits, thereby addressing industry pain points associated with traditional GaN devices—such as complex drive circuits, susceptibility to crosstalk and poor stability—and have become the core solution for high-frequency, high-power-density and high-efficiency power electronic equipment.

1. Core Technologies and Product Features

Compared to silicon, gallium nitride (GaN) offers a wider bandgap, a higher critical breakdown electric field and a faster electron saturation drift velocity, providing comprehensive advantages in physical performance. Leveraging these material properties, TI’s GaN power stage devices have achieved three major core technological breakthroughs: Firstly, ultra-low switching losses: with switching speeds far exceeding those of silicon MOSFETs, they support high-frequency switching operations of up to 2.2 MHz, significantly reducing energy losses during the switching process; secondly, ultra-high power density: the high-frequency operating characteristics enable a significant reduction in the size of passive components—such as transformers, inductors and capacitors—within power supply topologies, with system power density reaching up to 140 W/in³, which is 1.5 to 3 times that of traditional silicon solutions; thirdly, high efficiency and energy savings: system conversion efficiency can exceed 99 per cent, substantially reducing operating temperature rise and minimising the need for heat dissipation components.

Furthermore, TI’s GaN power stages utilise a proprietary integrated architecture, incorporating built-in dead-time control, anti-crosstalk design, and overcurrent and overtemperature protection. They eliminate the need for complex external matching circuits, resolving the issues of difficult drive control and poor stability associated with traditional wide-bandgap devices, and significantly lowering the design barrier for high-frequency power supplies. In addition, the devices support bidirectional power flow, making them suitable for new power topologies such as bidirectional energy storage conversion and photovoltaic grid connection, thereby meeting the innovative demands of the new energy sector.
